48 Method for generating of gear-shaped precision-working tools, in particular for regrinding shaving gears, and a gear-shaped tool, in particular a shaving gear, to which the method can be applied US61864 1993-05-14 US5377457A 1995-01-03 Herbert Loos; Manfred Erhardt
Gear-shaped precision-working tools, in particular shaving gears, capable of providing an optimum machining result only during a portion of their entire lifetime, since during each regrinding (generating), the profile displacement factor, and thus the number of the tooth flanks which engage successively and simultaneously one after the other the workpiece gear to be machined, is changed. This is remedied with the invention in such a manner that the precision-working tool is reground (generated) while maintaining the original number of teeth (z) and the original normal module of the pitch angle (.beta.), the module in transverse section and the base circle diameter are changed in such a manner that little or no change occurs to an original profile displacement factor (x). When the tool, which is to be reground (to be generated) in this manner, has grooved tooth flanks (12, 13), for grooves (14) increases continuously from a first groove (14') mutually adjacent one end of a tooth flank (12, 13) up to a second groove (14") mutually adjacent an other end of the same tooth flank, the grooves (14") having the greatest depth and the grooves (14') having the least on mutually adjacent and opposing tooth flanks (12, 13) opposing one another.

In a preferred form, the apparatus includes a radially oriented cutting ring adapted to engage a radially extending groove for removal of burrs from rear surfaces of the axially extending splines. Also in a preferred form, the apparatus includes a device for axially adjusting the position of the cutting ring relative to various lengths of splines to be deburred. Finally, in the same preferred form, a spring is employed to axially bias the workpiece against the cutting ring so that the workpiece may be resiliently displaced upon occurrence of force spikes during the deburring process.

53 Method for chamfering the edges of gear teeth US491126 1983-05-03 US4548531A 1985-10-22 Leon H. Seitelman; Edward J. Kaveckas
The ends of gear teeth are chamfered using an arcuate motion cutter having a complex cross sectional shape. In an improvement of the prior trial and error techniques, the cutter shape is made correctly the first time using an algorithm which includes determining certain s-dimensions produced on a chamfer by a set of tool dimensions; comparing these to the desired maximum, minimum and nominal chamfer widths, and; then iteratively optimizing the set of tool dimensions to minimize the differences.
